DUST AND SILENCER HOOD FOR VALVE-IN-HEAID MOTORS.

weenie.

To all whom it may concern:

Be it known that 1, CHARLES O. NORMAN, a citizen of the United States residing at Montgomery, in the county of ontgomery and State of Alabama, have invented certain new and useful Improvements in Dust and Silencer Hoods for Valve-in-Head Mo- 'Eors, of which the following is a specifica- This invention relates to accessoriesfor internal combustion engines, and pertains especially to an attachment for protecting and silencing valve-in-head motors.

The object of the invention is to provide internal combustion engines, or valve-inhead motors such as are commonly used for driving'automobiles, with an exterior at.- tachment forming a hood or inclosure for certain operating mechanism, and afiording protectionzof such mechanism against dust and all other foreign matter, fording expeditious facilities for lubrication, and for muflling the noise of the engine.

A further object of the invention to provide asupport for the hood or cover which shall constitute the bottom closure or base of the hood or cover, and which shall support and connect the hood or coverbers 4: and 5 and end membersfi which are with the engine.

A still further object of the invention is to provide a hood support of such construction as to aflord means for attaching the cover thereto, and as to afiord means for holding push rod tubes or. casings depending therefrom with the'upper' end of the tubes within the hood.

A still further object of the invention is to provide a cover or hood having a plurality of oil cups in the top thereof which shall register with a plurality of push rod casings having their upper ends within the hood, and a hood supportforming the bottom of the hood and having said casings extending therethrough for centralizing the casings in the hood with respect to all cups attached to the howd.

Various other objects, advantages and im proved results are attainable in the prac-. Ml

tical application of the invention as will be hereinafter fully set forth. In the accompanying drawings forming part of this application "Figure l is a perspective view showing Specification of Letters Patent.

the application of the invention as 'to a valve-ln-head engine.

' Fig. 2 is a cross section as in applied position, showing one of the push rod casings partly broken away.

Fig. 3 1s a top new of the supporting base. v

Fig. 4 is a detail perspective view showing a modification.

The same reference characters denote the same parts throughout the several views of the drawings.

My invention being specially applicable to internal combustion engines having overhead valves and exposed push rods, so much of such an engine is shown in the drawings as to illustrate the application of the invention, but the invention may be, shaped and fittedto any enginehaving said parts exposed;

In carrying out my invention Iemploy sheet metal of such weight and thickness as to readily admit ofv stamping into the desired shape for forming the hood or cover 1, and the base or support 2, for the hood.

The hood or cover 1, substantially comprises a top member 3, parallel side memcut out or sha ed at 7 to fit over two side end corners 0 an engine such as 8. The bottom edge of the side member 5 rests, upon the top of the engine so as to elevate the top of the hood above the engine and thereby form a space for the engine valves such as 9. The side member 4 extends below and isofi-set from the side member 5,so as ends of the motor, so that a portion of said the hood is applied thereto, with the hwd ends fitting over opposite.

opposite side 4, but said open porside of the engine and the valveiportion of the top of the motor are covered-zbyjthe hood. The hood is providedwi'th braces, straps 11, riveted-at. 11 to the inner face of the hood, and. said- 'straps have a projeeting end forminga ton e12,-

the purpose of which will be hereina er 98*,

v plained. The end members of the hood are inclined outwardly from the side member 4 to the side member 5 so as to produce flaring corners 1 at each end of thehood, whereby the hood is made to conform with the devices or parts to be housed bythe hood.

For'the purpose of supporting and connecting the hood with the engine, and for-- the purpose of closing the bottom of the hood, I have devised a special device which is an important feature of my invention. Said device comprises preferably a stamped out metal plate 13 forming a support for and closing the bottom of the hood. The

15 plate has depending side flanges 14 through of the side member 40f, the

- 17 for clamping bolts.18 and-an opening 19 nerface of the base.

for the i flexible tongues 30 in tion wire. The bolts 18 extend through t e plate 13 and preferably through stra s of the hood for securely clamping the 00d to the supporting base. A' In.- rality of holes 20 are made in the plate adiacent the inneredge thereof, and these ho es are provided with annular flanges 21, which hold the upper end of the push rod tubes orcasings 22. The ,caslngs or tubes extend through the holes 20 and have their'u per end within the hood 1. The lower en of thetubes 22 is enlarged and is provided with a shoulder 23 .and a neck 24. The top of the hood is provided with oil cups 25, one cup for each push rod 26, so that lubricat1on maybe expeditiously perfected without removing the hood.

Referring to Fig. 4, the hood straps 28 shown therein are provided with screw ends 29 adapted to extend through the su port- 1ng base and to have suitable nuts for dam ing the hood to the base. a

Fig. 5 shows a further modification of means for connecting the hood with the supporting base, by forming .or stampin the bottom .edge 0 the side 31 of the hood 32. .Said tongues adapted to be passed through slots in the supporting base and to be bent upon the in- Obviously in using f either of the modifications the clamping bolts hereinbefore described are not neces-. dispensed with m usm the modification shown in Fig. 5.

'. It w be seen that the hood as-applied to -valve-in-head motors completely mcloses r such valves and the ug ier portion of the pitsh rod casi so as to y protect them dust and other foreign matterinjurious to the i low the other side member,

same; that such inclosure mufiies o'r silences the noise of the motor under working condition; and that, by reason of the location of the oil cups lubrication is protected and facilitated.

It will also be seen that the invention is exceedingly simple in construction and application, and that the (parts thereof may expeditiously assemble do not wish to be understood as confining my invention to any 1p-ei'lrticular size or materlal, nor do I wish to it myself in the application of the invention to any particular ca acity of the hood, or to the number of pu5 rod casings held by the su porting base of the hood, neither do I wish to confine myself to any particular means for attaching the supporting base-to a motor, but reserve the ri ht to make such changes and variations in e manufacture and ractical application of the invention an the parts thereof, as may be considered within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:-

1. A hood for valve-in-head motors, comprising a longitudinal side member for engaging the top of the motor a longitudinal side member off-set from and depending bea to member connecting the side members, en members having a cut out portion fitting a corner of the motor, a base extending laterall from the side of the motor for closing the ottom of the hood, and means for attaching the depending side of the hood to the base.

2. The combination with a. oneiece hood for valve-in-head motors, and a 00d supporting base having slots, of straps attached to the hood and having tongues proglecting from the hood for engaging the ots.

3. The combination with a hood for valve-in-head motors, and a hood-su porting base having slots, of straps atta ed to the hood and having one and de ding from one side of the hood and orming tongues for en g the slots. 4. The comEination with a hood for valve-in-head motors, ing base adapted to fit and ha from one SldQ of the hood and extending through the slots.

5. e combination. with a hood for y'alve-in-head motors, and a hood-supportmg base adapted to fit one side ofthe motor and ham slots, of tongues depending from one side of the hood and extending through the slots, clamping bolts for securmg the hood to the base, and bolts for securm the base to the motor.

6. ecombination with a hood for and a hood-supportone side of the motor slots, of tongues depending 7 waIVe-in-head motors, a hood-supporting meson base attached to the motor, a plurality of push rod casings extending through the base and projecting into the hood, and oil cups secured to the top of the hood opposite 5' the upper end of the casings.

7. The combination with a hood for va1vein-head motors adapted to have one side member supported by the top of the motor, and a portion of this side thereof 10 closed by application to the motor, and inclined hood ends having a cut out, of a supporting bottom fitting the said closing side of the motor and having the other tide of t the hood resting thereon, a lurality of push rod casings held by said ottom and pro- 15 jecting into the hood, means for connecting the hood with the bottom, and means for connecting the bottom with the motor.
